I have heard, repeatedly, that "certain" powders, require 20% more, by volume, to get the same results as commercial powder. No problem in a long gun, but what about cap-n-ball revolvers. Will revolver champers hold 20% more. I have not yet tried any, nor have I tested a chamber to see if a load 20% larger will leave room for a projectile (round balls are all I use). Thanks.
